The discovery of gravitational waves

After 100 years of searching, an international team of physicists has confirmed the existence of Einstein's gravitational waves, marking one of the biggest astrophysical discoveries of the past century. It's a huge deal, because it not only improves our understanding of how the Universe works, it also opens up a whole new way of studying it.

The discovery of these waves, created by violent collisions in the universe, excites astronomers because it opens the door to a new way of observing the cosmos. For them, it’s like turning a silent movie into a talkie because these waves are the soundtrack of the cosmos.

Scientists struggle to stay grounded after possible gravitational wave signal

Not for the first time, the world of physics is abuzz with rumours that gravitational waves have been detected by scientists in the US.

Lawrence Krauss, a cosmologist at Arizona State university, tweeted that he had received independent confirmation of a rumour that has been in circulation for months, adding: “Gravitational waves may have been discovered!!”

The excitement centres on a longstanding experiment known as the Advanced Laser Interferometer Gravitational-Wave Observatory (Ligo) which uses detectors in Hanford, Washington, and Livingston, Louisiana to look for ripples in the fabric of spacetime.
